Back a couple of weeks ago, there was a thread started about storing testing reagents in a refrigerator. I gave it a big thumbs up, because I've been storing my reagents in the "beer" fridge in my garage since I bought the kit, and never had a problem. Of course, there were some dissenting opinions, so I decided to go to Taylor and ask them (if you want a clear drink of water, go to the head of the stream). Wellllll, it looks like I'm eating crow dumplings tonight. Taylor sent me the attached bulletin, and recommended that I not refrigerate my reagents, as the sudden change in temperature from the refrigerator to the outdoors causes the reagents to deteriorate.
Hope this helps,
